I have downloaded PyDsTool for Windows. And I believe I have pointed python in the correct location. But I get the following error

import fixedpickle as pickle
ImportError: No module named fixedpickle
I solve this problem through uninstalling and reinstalling anaconda. Otherwise the installation of PyDsTools is very simple. It is not really installation at all, just unpack the zip folder and make sure it is in your python path (also add its parent directories to the python path). This may be done through Spyder IDE. Click tools> pythonpath
I received some assistance from the Sourceforge support thread for the PyDStool project here

ImportError: DLL load failed: The file cannot be accessed by the system.
Got this error while trying to run some already used python scripts on pycharm. Has anybody had this error before and has he solved it? It started after I installed a package in python but never used it. The problem is located when I try to import train_test_split on scikit-learn and tensorflow, the sklearn package and seaborn. The other parts of the code seem unaffected.
I have already reinstalled anaconda and python as well as changing the python files. Any help would be greatly appreciated.
After reinstalling the python as well as updating all the packages (conda update --all) and changing the PATH file, it seems that the issue is solved in all of my IDE's except PyCharm. It seems that all that remains is an interpreter issue. I will post updates if something else comes into my attention.
I am trying to use tensorflow for research in my macbook. I use pip3 to install tensorflow in the system (not in virtual environment).
At first, I just want to verify tensorflow can be correctly imported via python3 in terminal. However, sometimes, I got the following problem when importing.
>>>import tensorflow as tf

This error could only be solved if I ran the following code firstly before python3 execution
unset PYTHONPATH
If I didn't unset PYTHONPATH, I also found errors when checking the version of pip3 using
pip3 --version
The errors are shown as follows.

raise ImportError('This package should not be accessible on Python 3. '
ImportError: This package should not be accessible on Python 3. Either you are trying to run from the python-future src folder or your installation of python-future is corrupted.
I thought it was so inconvenient to unset PYTHONPATH every time, so is there any solutions for this problem? I also want to import tensorflow in other text editor, such as Sublime and Pycharm, so I was really not sure what to do next.
I tried the same scenario. It is working fine for me. In the first error it seems your python installation is messed up. If you are using python3 in terminal, it should not refer to 2.7 libraries.
Also I dont think you require unset PYTHONPATH everytime. First thing is you dont need to setup PYTHONPATH. It seems the installation got issue.
You using homebrew in mac to install packages. If not I will say use homebrew and it will work as charm. As it adds dependency properly.
Thanks,
Ashish

Since then the only change I have made is to install the macOS Supplemental Update and to upgrade Python from 2.7.13_1 to 2.7.14_2 (using Homebrew). I have changed the relevant linker flags in the makefile, i.e. those that appear when I type python-config --ldflags. I have also made sure that the Python I am using is definitely the Homebrew one by inserting export PATH="/usr/local/opt/python/libexec/bin:$PATH" into my .bash_profile as directed by Homebrew.
I am not sure whether this error is because of the Python update, the recent macOS Supplemental Update, or something else. Any idea what the problem could be?
Thanks
I had the same problem;
In python 2.7 the NumPy 1.8.0 was available,
Then I installed NumPy (again) using brew, and it wasn't available in my python (2.7) anymore. (Got the same error you got here)
So I did "brew unlink python && brew link python" to use python 3 (instead of 2) which NumPy 1.14 is available in it.
I guess the python 2.7 was not compatible with this recent version of NumPy.

I use Python 3.2.3
Tonight I tried to install requests from http://docs.python-requests.org/en/latest/ by pip and easy_install, but it doesn't work. I have error when trying to import it. So I decided to use standard library urllib.request and see this error again
That is the traceback:

ImportError: Module use of python26.dll conflicts with this version of Python.
So how can I fix this?
UPD: Solved. It was bug in SublimeREPL, reinstalled that package.
I had a similar problem when I was using PythonXY. The Spyder was not loading and it turns out another software OpenCAD had installed Python2.6 version and that was not letting my Python27.dll to not work. After uninstalling OpenCAD, I was able to run the software.
I was able to troubleshoot by first searching for python26.dll and found that this file was located in the OpenCAD folder location and that made me realize that this software was causing the issue.
